Episode Details

I'm not trying to speak ill of the dead but Leo went bird watching at a LANDFILL and contracted the deadly hantavirus. Also, not just the virus, a RARE strain of the virus that can be transmitted person to person. He then boards a cruiseship and proceeds to infect pretty much the entire ship.
.. Don't hang out in landfills, guys. For doing something that when you think about it, it a reallllllllllly bad idea, Leo should feel shame, shame, shame.
